摘　　要：特高含水期(含水大于90%)是注水开发油田的重要阶段,该阶段仍有较多储量可供采出。我国注水开发油田大多经历了几十年的开发与调整,绝大部分油田已进入注水开发后期,多数油井含水高达95%以上。虽然面临油层水淹严重、剩余油分布高度分散等问题,但水驱油藏仍在开发中占主导地位。通过对国外注水开发油田的调研,分析特高含水期采取的主要技术措施,对改善水驱开发效果,提高采收率进行了探讨,为我国水驱开发油田特高含水期的开发工作提供借鉴和指导。It is an important stage for a water drive oilfield when the water cut reaches 90%, and the remaining oil reserves st-ill play an important role in this period. Most of the oilflelds in China are producing in later high water cut stage after a long time development and the water cut of most wells has been beyond 95%. Although the production layer is highly flooded and the distribution of remaining oils is rather highly dispersive, water flooding s still a main method of enhanced oil recovery, This paper summarizes successful experiences and useful methods n many different aspects in foreign high water cut oilfields, from which, Chinese should learn more to develop and manage ~ater high water cut oilflelds
